For the first time, a new dosimetry system is presented that combines a synthetic diamond detector with a customized front-end and acquisition electronics, specifically designed for UHDR electron beam diagnostics. The system enables real-time measurements of pulse duration with a resolution of ±8 ns, supports pulse charge values up to 40 nC with a resolution of 10 bits, and provides instantaneous estimates of the dose rate in the order of MGy/s. These features enable accurate quantification of pulse parameters and cumulative dose, making the system a reliable tool for UHDR beam characterization. This makes the system a robust tool for UHDR beam characterization and a key resource for the commissioning of FLASH-compatible LINACs, with direct application in preclinical radiotherapy research.
We believe this system brings precision, speed, and reliability to this cutting-edge field, helping to bridge the gap between research and the clinical application of FLASH-RT.
